Aptidão do solo para produção de cana - de ̵ açucar em Moçambique

Abstract

In order to analyze the edaphic and climatic requirements of sugarcane and to indicate in a general way the existence of suitable conditions for its cultivation in Mozambique, an investigation study was carried out of the locally existing literature, foreign literature and some personal communications at sugarcane production sites From the information obtained, tables were constructed that indicate, in a tentative way, the criteria for the qualitative assessment of the edaphic and climatic conditions. The soils currently used for sugarcane in Mozambique are Eutric Fluvisols and Vertisols: soils from large river valleys. These soils have high natural fertility, capable of maintaining production without breaks for up to approximately 2 years. Despite the scarcity of information on dryland sugarcane production in Mozambique, it can be concluded from this work that there are adequate climatic and edaphic conditions that can be used rationally for the introduction of dryland sugarcane in the Provinces. Niassa and Zambézia without appreciable risks, But this is not confirmed with practice data on a business scale. And to ensure better results in terms of sugarcane production yields in these provinces, chemical fertilizers and organic fertilizers must be applied to the soil in order to increase its agricultural potential. The amount of fertilizers and fertilizers to be applied will depend on the analysis of the respective soils. Given the scarcity of local information, it is recommended that: 1) trials to test sugarcane varieties in different types of soil and environmental factors to observe yield variation and resistant varieties; 2) trials to test the yield variation between dryland sugarcane and irrigated sugarcane;
